Analysis of a novel cylindrical 3-DoF parallel robot

In this paper, a novel three degrees of freedom (DoFs), that are two degrees of translational freedom and one degree of rotational freedom, parallel robot is proposed. The parallel robot consists of a base plate, a movable platform, and three connecting legs. Because the locus of any point on the moving platform is the subset of a cylinder if z is specified, the robot is called a cylindrical parallel robot. The inverse and forward kinematics problems are described in closed forms. And the velocity equation of the new parallel robot is given. Three kinds of singularities are presented. The workspace for the robot is analyzed systematically, especially, a new index to evaluate the mobility (In this paper, mobility means rotational capability.) of the moving platform of the robot is defined and discussed in detail. The parallel robot has wide application in the fields of industrial robots, simulators, microrobots and parallel machine tools.

A Novel Spatial Three Degrees of Freedom Parallel Manipulator

In this paper, a new spatial three degree-of-freedom, that are two degrees of translational freedom and one degree of orientational freedom, parallel manipulator is proposed. The parallel manipulator consists of a base plate, a movable platform, and three connecting legs. The kinematics problems and velocity equation of the new parallel manipulator are given. The three kinds of singularities are presented. The parallel manipulator has wide application in the fields of industrial robots, simulators, micromanipulators, and parallel kinematics machines.

On the analysis of a new spatial three-degrees-of-freedom parallel manipulator

In this paper, a new spatial three-degrees-of-freedom (two degrees of translational freedom and one degree of rotational freedom) parallel manipulator is proposed. The parallel manipulator consists of a base plate, a movable platform, and three connecting legs. The inverse and forward kinematics problems are described in closed forms and the velocity equation of the new parallel manipulator is given. Three kinds of singularities are also presented. The workspace for the manipulator is analyzed systematically; in particular, indices to evaluate the mobility (in this paper, mobility means rotational capability) of the moving platform of the manipulator will be defined and discussed in detail. Finally, a topology architecture of the manipulator is introduced. The parallel manipulator has wide application in the fields of industrial robots, simulators, micromanipulators, and parallel machine tools.

International cooperation and trends in the field of industrial robots

SUMMARYAfter discussing the advent of the Age of Automation, the author considers the number of robots in operation throughout the world and the forecasts of their manufacture for each country. Attention is then drawn to the international exchange of research and technological information, in particular to the frequent symposia on industrial robots (ISIR). In addition to ISIR, international conferences on advanced robotics are also envisaged (ICAR). Finally, some details are given of international cooperation in the realm of industrial research.

Government sponsored research in the field of industrial robots in the Federal Republic of Germany

In May 1974, a new research programme entitled “Humanization of Working Life” was published by the Ministry of Research and Technology of the Federal Republic of Germany. Its aims are to temper and to reduce the hindrances, damage, harassments and handicaps of working life. What is involved here is an improvement in the content of work and in relationships at work, i.e. entire working processes are to be reformed comprising both organisational and control functions. Moreover, facilities are to be created for improved communication and co‐operation between workers. Situations leading to both over‐stress and lack of stress are to be reduced insofar as they are caused by the harmful effects of noise, vibrations, dangerous substances, etc. as well as by too few or one‐sided mental demands. Special attention is to be paid to any stresses of a combined nature that might occur and their effects. The number of accidents at work is to be cut by improving safety at work. Finally, the reciprocal relationships are to be examined, within the framework of the research programme, between working life and other aspects of life; and strategies will be developed for further humanization of working life by taking into consideration numerous other factors of a political, economic and technical nature.
